- # Demo Certificates
-
- This directory contains certificates used by the clients and servers in our
- sample programs. These certificates are for testing purposes only and should
- **never** be used in a production environment.
-
- As provided, the server certificates use `127.0.0.1` for the Common Name, the
- IP address and DNS name. This works fine when you run the client and server on
- the same host. However, if you want to run them on separate hosts, you may need
- to regenerate the certificates. (This is especially true for the JavaScript
- examples.)
-
- We've included the Python script `makedemocerts.py` to simplify this task.
-
- ## Prerequisites
-
- You'll need Python to run the script. The script also depends on a utility
- package from a separate [ZeroC repository][1]. You can install this package as
- follows:
-
- ```
- pip install zeroc-icecertutils
- ```
-
- ## Usage
-
- Running the script with `-h` displays the following usage information:
-
- ```
- Usage: certs/makedemocerts.py [options]
-
- Options:
- -h Show this message.
- -d | --debug Debugging output.
- --ip <ip> The IP address for the server certificate.
- --dns <dns> The DNS name for the server certificate.
- --use-dns Use the DNS name for the server certificate common
- name (default is to use the IP address).
- ```
-
- The `--ip`, `--dns`, and `--use-dns` options affect the generation of the server
- certificate. Without any arguments, the script prompts for the value of the IP
- address and DNS name.
-
- You can specify an alternate IP address using `--ip` and an alternate DNS name
- using `--dns`. The `--use-dns` flag forces the script to use the DNS name as
- the server's Common Name instead of the IP address.
